PIPE-SUPPORT FOR ASH-CONVEYING SYSTEMS.

Specification of Letters Patent.

Patented Mar. 8, 1921.

Application filed June 21, 1919. Serial No. 305,723.

To all whom it may concern Be it known that I, ARTHUR P. STRONG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Pipe-Supports for AshC onveying Systems, of which the followlng 1s a specification.

This invention relates to improvements in conveying systems for ashes or like materials and more particularly to a supporting device or frame, especially adapted to support the permanent pipe sections of an ash conveying conduit, and to permit the necessary removal and replacement of certain pipe sections or fittings which have become Worn by the abrasive action of the materials, without disturbing the alinement or position of said permanent sections of the conduit.

In systems of the character described, the passage of ashes or like abrasive materials through the pipes produces wear, owing to the abrasive action that is present, the degree of wear varying throughout portions of the conduit, it being evident that the maximum wear or effect of the abrasive action is manifested at the turns or bends in the conduit and in the straight portions of the conduit immediately adjacent. As a result it has been found advantageous to employ fittings and pipe sections at these points in the conduit which are capable of removal and replacement. In order to facilitate in the removal and replacement of the worn sections of the conduit, it is desirable to provide a suitable supporting device which will support the permanent pipe sections of the conduit and maintain them in fixed angular relation and proper alinement during the operation of replacing the worn sections.

The object of the invention is therefore to provide a construction for a device of the nature above indicated. that will accomplish the desired result in the simplest and most efficient manner, together with certain other objects and advantages as will hereinafter be more fully pointed out in connection with a detailed description of one form of the device embodying the invention, which is fully illustrated in the drawings, wherein Figure 1 shows a side view of the device and a portion of the conduit or pipe sections supported thereby;

Fig. 2 is an end view of the supporting frame with the pipe sections removed;

Fig. 3 is a top view of the supporting device taken on line 3-3 of Fig. 1, and shows the method of connecting the vertical portron of the conduit to the supporting device;

Fig. 4 is a similar view showing the end of the supporting device with pipe sections removed;

Fig. 5 is a cross-sectional view of the supporting frame taken on line 55 of Fig. 1:

Fig. 6 is a side view of the lower portion of the supporting device taken on line 66 of Fig. 1; and

Fig. 7 is an enlarged detail view taken on line 77 of Fig. 3, showing a special type of bolt used as means for connecting the pipe sections to the supporting device.

A suitable construction for the device embodying the features of my invention is herein illustrated and described in connect1on with a portion of an ash conveying conduit, comprising a vertical pipe or riser 10 and a horizontal pipe 11, arranged at right-,

angles to each other and which are connected together by means of an elbow fitting 12, the same being provided with end flanges of the standard form and adapted to be connected by means of bolts to the adjacent sections, which are provided with similar end flanges. As clearly illustrated. in the drawings, the supporting device consists of a framed structure, erected in upright position adjacent a bend in the conduit consisting of the pipe sections 10 and 11 of the conduit (which are here considered as the permanent sections) and the elbow fitting 12. The supporting frame is preferably constructed of structural iron or steel and arranged to surround or include a part 1 of the vertical portion of the elbow 12 and terminating adjacent to the end of the vertical riser or pipe section 10 of the conduit. The frame rests at its base upon a floor or is otherwise fixed to a suitable support, said 1 4 frame being also fixed to the permanent pipe sections 10 and 11, there being provided suitable connecting means hereinafter fully set forth.

Referring now more in detail to the con 1 ing connected together by the usual form of rivets. A plurality of short angle members 17 riveted to the plates 16 at the lower corners of the frame provide a suitable base for anchoring or bolting the frame to the floor or other supporting frame. A series of horizontal plates 18 are preferably pro- .vided, which extend between the several vertical members 14 at a point intermediate the upper and lower ends thereof to provide additional strength to the frame.

Additional members for connecting the permanent pipe sections to the supporting frame may be described as follows: Two transverse angle members 20, 20 extend across the upper end of the supporting frame and are riveted to the cross-members 15, 15, said angle members being spaced apart in parallel relation, as shown in Figs. and 4, there being provided curved cut-out portions 21 to form circular opening for the pipe 10 and bolt holes 22 to receive the connecting bolts. A somewhat similar arrangement is employed at the lower portion of the frame for supporting the horizontal section 11, namely, two horizontal angle members 23, 23 riveted to the upright frame members 1 1 and extending a distance beyond the frame. Extending between the ends of the members 23 is a crossbar 2% (Fig. 6) rigidly connected by means of rivets, said cross-bar having a downwardly facing, curved recess to receive the pipe 11 and properly placed bolt holes 26, through which extend the bolts used in connecting the pipe section to the cross-bar 241.

As before indicated, the portions of the pipe line or conduit supported by the frame 13 comprise, in general, the vertical riser 10, the horizontal section 11, and the intermediate elbow fitting 12, although a preferable arrangement is to provide. a comparatively short straight section 27 intermediate theelbow fitting 12 and th'e vertical riser 10, said section "being capable of re- ;movalindependently of the elbow, thus per 'mittin'g either or boththe'elbow or a straight .portion of thepipe immediately beyond to be removed and replaced. I

In order to permit the-convenient removal of the pipe sections, a'ispecial type of bolt and connecting means are used, as will be understood fromthe description of the same,

in connection .with. the vertical pipe section 10, and the method of connecting the same to the upper end of the frame. The'end' of the permanent pipe section 10 is held in abutting relation with the adjacent remov able section,. by the use of :a plurality of lugs 28, spaced about the end of the section 10 (Fig. 7) and corresponding lugs 29 integral with the pipe section 27. These lugs have longitudinal webs 30, spaced apart and extending therefrom toward the ends of the pipe sections. The lugs 28 of the pipe section 10 abut against the under surface of the cross-members 20, and are provided with bolt holes which register with the bolt holes 22 in said cross-members. Through these bolt holes and also through bolt holes in the lugs 29 extend bolts 31, the same being comparatively long and having intermediate their ends a square head 32 adapted to be retained between the webs 30 of the lugs 28 to prevent the bolts from turning. The upper and lower ends of the bolts are threaded and carry nuts 33 and 3 1, respectively, the nuts 33 and the square head 32 connecting the pipe section 10 to the cross-members 20, and the nuts 34 holding the section 27 in abutting connection with the section 10 and at the same time permitting the section 27 to be removed, by taking off the nuts 34, without disconnecting the permanent-section 10 from the frame. Substantially the same form of connection is used in connecting the horizontal pipe section to the elbow 12.

In order to facilitate the removal of the elbow 12 and pipe section 27, there is preferably provided, immediately adjacent the flanged ends of the elbow, two comparatively short pipe sections 35 and 36, the former being, in fact, apart of the straight section 27, and the latter being intermediate the end of the horizontal pipe section 11' and the elbow 12. The short section 35 of the straight section 27 is connected thereto by a duplication of the form of connection herebefore described; namely, by a plurality of lugs and bolts, as indicated by 37. The purpose of this construction is to enable the removable sections to be more easily removed, inasmuch as these short sections can be'withdrawn, thus giving the necessary space and freedom of'movement for removing the larger sections. This feature, however, forms no part of this invention and therefore will be omitted from the present discussion.

Itis clear from this description that the supporting frame or device serves a number of purposes whereby certain advanta- "geou's results "are obtained that may be pointed out. First, the device provides a supporting means for parts of the conduit 7 and particularly the heavier portions includin the fittings and additlonal weight w that would ordinarily be present at thebends and angles in the conduit, and as such is capable of being anchoredfto the floor or other foundation, as shown in the drawings, or suspended from the ceiling or frame of a buildingor by slight modification attached to the side walls of a building. Secondly, the frame serves as means for connecting the parts of the conduit together during the operation of replacing the worn sections and in so doing maintains the permanent sections of the conduit in perfect alinement and fixed relation, thus obviating the possibility of any disturbance or disarrangement in the piping of the system or the necessity of providing other temporary supports and connections for the permanent pipe sections during the operations. And, thirdly, it provides a means for facilitating the easy and quick removal and replacement of the worn sections of the conduit, thereby adding greatly to the efficiency of the conveying system by avoiding long stoppage in operation in making the necessary changes, as well as the cost of time labor in maintain ing the system in proper operating condition.

The structure, so far as herein set forth and illustrated, embodies my invention, which may be further considered in connection with the accompanying claims.

I claim as my invention:

1. In conduit, the combination of two pipe sections arranged at an angle to each other, and a rigid frame connected with both of said pipe sections for supporting and maintaining the same in their angular relation.

2. In a conduit, the combination of two pipe sections arranged at right-angles to each other, and a rigid frame connected with both of said pipe sections for supporting and maintaining the same in their angular relation.

3. In a conduit, the combination of two permanent pipe sections spaced apart and arranged at an angle to each other, a removable pipe section inserted between and secured to said permanent pipe sections, and a rigid frame connected with both of said permanent pipe sections for supporting and maintaining the same in their angular relation.

In a conduit, the combination of a riser and a horizontal run of pipe, a removable pipe section inserted between the lower end of the riser and the adjacent end of said horizontal run of pipe, and a rigid frame connected with said riser and the horizontal run for supporting the same and holding them in their angular relation.

5. In a conduit, the combination of a riser and a horizontal run of pipe, a removable pipe section inserted between the lower end of the riser and the adjacent end of the horizontal run of pipe, and a rigid frame, comprising an upright portion connected with said riser adjacent its lower end, and a horizontal portion connected with the horizontal run adjacent the end to which said removable pipe section is secured, said frame serving to support both the riser and the horizontal run and hold the same in their angular relation.

6. In a conduit, the combination of a riser and a horizontal run of pipe, a removable pipe section inserted between the lower end of the riser and the adjacent end of the horizontal run of pipe, and a rigid frame, comprising an upright portion composed of a plurality of upright supporting posts connected with said riser adjacent its lower end, and a horizontal portion secured to said posts and extending outward therefrom and connected with the adjacent end of the horizontal run of pipe, said frame serving to support both the riser and said horizontal run of pipe and hold the same in their angular relation.
